Living in Mumbai is a dream for many, but for lakhs of residents, that dream has been shadowed by a missing piece of paper: the Occupation Certificate (OC). Across the city, thousands of housing societies have found themselves trapped in a legal and financial limbo because their developers abandoned projects or failed to complete minor procedural paperwork.
In a major relief move, the Brihanmumbai Municipal Corporation (BMC) introduced the BMC OC Amnesty Scheme. This initiative acts as a structural lifeline for residential societies trying to regularize their status and secure their legal property rights.
If your building has been stuck without an OC for years, here is a breakdown of what the OC Amnesty Scheme means for you, who qualifies, and how it can drastically improve your financial peace of mind.
The OC Amnesty Scheme is a targeted policy designed to help housing societies independently secure their Occupation Certificates in cases where the original builders or developers defaulted. By offering critical financial concessions and streamlining approval processes, the BMC aims to bring formal, legal status to nearly 25,000 residential buildings, directly benefiting roughly 12 lakh homeowners across the Mumbai metropolitan area.
The scheme is a one-time regularisation initiative for buildings occupied without an OC prior to the cut-off date, provided they had sanctioned development permissions at the time of construction. It is meant to resolve legacy OC issues at reduced cost, with significant implications for property transactions, financing, redevelopment, and disputes arising from historic defaults by developers.
The scheme is highly beneficial, but it is strictly regulated to prevent the abuse of safety standards. To qualify, your building must meet the following parameters:
The building must have been physically occupied on or before November 17, 2016. This revised date extends eligibility from the earlier January 6, 2012 deadline, covering a much larger pool of pre-2016 buildings.
The structural project cannot be entirely unauthorized. The society must prove that the building originally received standard baseline permissions, specifically:
A valid Intimation of Disapproval (IOD) and a Commencement Certificate (CC)
Approved building plans from the BMC
Over 50% of the building's total area must be designated for residential use. Specific institutional structures, such as recognized schools and hospitals, may also qualify under the scheme.
Maximum concessions and penalty waivers are explicitly reserved for residential flats with a carpet area of up to 80 square metres (approximately 861 sq. ft.). Larger luxury apartments are generally excluded from these specific financial relief brackets.
The amnesty scheme is not a blanket pass for illegal construction. The BMC will not regularize:
Major, hazardous unauthorized alterations, such as illegal vertical floors added without permission or horizontal expansions extending well beyond the approved building lines
Buildings constructed without the necessary approvals (no IOD, no CC, no sanctioned plans)
Structures that fail to meet fire safety norms and structural stability certificates—safety compliance remains non-negotiable and must be met before an OC is granted
For decades, occupying a building without an OC has meant bearing heavy financial penalties. Successfully applying under this scheme unlocks massive advantages:
Buildings without an OC are often hit with heavy penal rates for basic utilities. Getting an OC puts an end to double property taxes and inflated, penal water and sewage charges. Under the scheme, property tax would be calculated at the BMC's specified rates instead of penal rates.
Selling a flat in a non-OC building is incredibly difficult. An OC instantly boosts property value and makes it fully marketable to prospective buyers. The scheme improves buyer confidence and reduces legal uncertainty in property transactions.
Major banking institutions are hesitant to fund properties lacking an OC. Securing this certificate opens up clean access to institutional refinancing and fresh home loans.
Housing societies cannot easily gain legal ownership of the plot of land (conveyance) without an OC. This scheme clears the primary hurdle holding up the society's Deemed Conveyance application.
The scheme provides a 50% concession on various charges, including:
Regulation fees
Penalties for eligible deviations (balcony enclosures, otlas, lofts)
Application costs
Premium for additional and fungible compensatory FSI (calculated at prevailing Ready Reckoner rates)
The BMC has made the application process largely online through the Auto-DCR portal, with a dedicated "OC Amnesty Scheme" section. Here's what you need to do:
Before applying, ensure your managing committee has the following ready:
Valid IOD and CC
Approved building plans
Property tax assessment records
Proof of occupancy before November 17, 2016 (electricity bills, property tax receipts, or other official documents)
Society registration proof
Conveyance documents (if available)
Applications must be filed through registered architects or licensed surveyors. Individual flat owners can also apply in certain cases, not just societies or developers.
To avail of the zero-penalty benefit, submit your application within the first six months of the scheme's official launch. Note that while the policy framework is approved, the official implementation date may still be announced—societies should prepare in advance to act quickly.
After submission, the BMC will verify documents and conduct necessary inspections to ensure compliance with safety norms, including fire safety and structural stability. Once cleared, the OC will be issued.
This is a one-time opportunity. Once the window closes, buildings that fail to apply may lose the chance to regularize under these concessional terms.
While the scheme offers financial relief, it does not waive mandatory safety and regulatory checks. Fire NOC, structural stability certificates, and other safety compliances must still be obtained before the OC is granted.
The policy framework explicitly states that it does not legalise unauthorised construction. Only buildings with approved plans and valid baseline permissions qualify.
Housing societies whose buildings were occupied on or before November 17, 2016 and had an IOD, CC and approved plans. In certain cases, individual flat owners can also apply.
A 50% concession on regulation fees, penalties for eligible deviations, application costs and the FSI premium.
No. Buildings without an IOD, CC or sanctioned plans, and those with major unauthorised alterations, are excluded.
Through a registered architect or licensed surveyor, via the "OC Amnesty Scheme" section of the BMC's Auto-DCR portal.
The BMC's OC Amnesty Scheme shifts the power back into the hands of Mumbai's housing societies, allowing residents to bypass defaulting builders and take charge of their own properties. If your building falls within the pre-2016 timeline and meets the baseline criteria, it is highly recommended to:
Gather your managing committee and audit your original building approvals
Consult a structural engineer or legal advisor to initiate your application
Prepare all documents in advance so you can apply the moment the scheme goes live and make the most of the early-bird benefits.
For the estimated 58,000 buildings across Mumbai awaiting Occupation Certificates, this amnesty scheme could finally remove long-standing obstacles to property transactions, redevelopment, and legal documentation. Don't wait for the launch date to start preparing—the societies that act early will benefit the most.
